Diagnostic description. Body length 3.35–5.02 mm (most specimens> 4.0 mm), body width 1.50–2.22 mm. Ratios: pronotum length / width 0.81–0.87, elytra length / width 1.55–1.63, length elytra / length pronotum 2.57–2.69. Of medium size. Elongate. Upper side brown, pronotum opaque, elytra somewhat lustrous; legs and antennae brown. Eyes touching each other on frons. Penultimate antennomere drop-shaped and somewhat elongate (length/width 13: 9). Pronotum widest in middle, towards hind corners more or less narrowed, sometimes slightly emarginate in front of hind corners; lateral margins flat; punctures on surface very dense and of medium size. Elytra elongate oval, with eight rows of large, dense punctures, intervals with narrow carinae; these carinae present one row of short hairs on each side (hairs well visible at 25× magnification). For aedeagus see Fig. 4b.

Differential diagnosis. Gonocnemis sumatrensis is similar to G. evidens Bremer, 2006 from Thailand which has the same form of antennae. On average specimens of this species are smaller (body length 3.4–4.3 mm). In contrast to G. sumatrensis the sides of pronotum of G. evidens present nearly the same width in their middle and at their base. Gonocnemis evidens has shorter hairs on elytra than G. sumatrensis (the posteriorly inclined hairs alongside the carinae approach the base of the next hairs, in G. sumatrensis they overlap the base of the next hairs); the elytral carinae on intervals are missing on the first three to four intervals in G. evidens , they are low and narrowly visible on these intervals in G. sumatrensis .

Distribution. Borneo and Sumatra ( ARDOIN 1964d).
